Reaction Steps
In 50 ml of dichloroethane were dissolved 5.8 g (0.05 mole) of levulinic acid and 10.26 g (0.06 mole) of monochloroacetic anhydride. To the resulting solution were added 8.98 g (0.065 mole) of 1,2-dimethoxybenzene and 0.71 g of boron trifluoride-diethyl ether complex and the resulting mixture was then stirred at 50° C. for 5.5 hours. After completion of the reaction, the reaction solution was cooled and washed successively with water, 5% aqueous sodium carbonate solution and water. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to obtain 9.66 g of 4-(β-acetylpropionyl)-1,2-dimethoxybenzene.
